Acoustic and elastic least-squares two-way wave equation migration with exact adjoint operator
DownloadSpring 2017
A major problem in exploration seismology entails estimating subsurface structures and properties via linearized inversion. The problem is often called ''least-squares migration" where seismic imaging is posed as an iterative least-squares problem. The iterative solution employs the method of...

Efficient algorithms for least squares wave equation migration and source signature estimation
DownloadFall 2017
Estimating accurate images of the subsurface is one of the end products of seismic data processing. Numerical solutions to the wave equation allow designing linearized forward operators. The adjoint of the linearized forward operator is used to image the interior of the earth. The adjoint...

Electrical Resistivity Structure of the Altiplano-Puna Magma Body and Volcan Uturuncu from Magnetotelluric Data
DownloadFall 2015
An intense episode of silicic volcanism in the Southern Altiplano over the past ten million years has created a major volcanic province in the Central Andes known as the Altiplano-Puna Volcanic Complex (APVC). Geophysical evidence indicates that magma is still present in a large mid-crustal...

Landslides have occurred throughout the Holocene geologic epoch and they continue to occur in the Peace River Lowlands of Alberta and British Columbia. This study was conducted to provide an understanding of the processes and extents of one such landslide situated on a major slope at the Town of...

This thesis proposes a framework for ground roll removal based on regularized inversion. Both ground roll and reflections are represented in the frequency-space (f - x) domain as a linear function of unknown complex amplitudes. An inversion algorithm is developed to estimate the coefficients that...

Magnetotelluric Imaging of Electrically Anisotropic Crust Near Fort McMurray, Alberta: Implications for Engineered Geothermal Systems
DownloadFall 2014
The goal of this thesis is to investigate the character of the basement rocks beneath the oilsands region around Fort McMurray in the context of developing engineered geothermal systems (EGS). Magnetotelluric (MT) data were collected at 94 stations on two profiles near to Fort McMurray and...

This thesis uses the magnetotelluric (MT) method to image the electrical resistivity structure of the Laguna del Maule Volcanic Field (LdMVF) and the regional subduction zone structure of central Chile (36°S) in the vicinity of the 2010 Maule earthquake. The LdMVF surrounds the eponymous Laguna...

Magnetotelluric Investigations of the Tintina Fault Zone for Geothermal Exploration at Watson Lake, Yukon
DownloadFall 2023
Geothermal energy is being investigated as a renewable source of electricity and heat production for communities in northern Canada. The successful development of a geothermal energy project requires three key components: (1) there must be a source of sufficient heat at near-surface depths....

Convergent plate boundaries have played an important role in the growth and assembly of the modern continents. To obtain a better understanding of the tectonic processes in these boundaries, it is necessary to constrain the rheology of the crust and upper mantle in these regions. Magnetotelluric...

Arc-continent collisions are a fundamental plate tectonic process that control continental growth, orogen development and the distribution of natural hazards and natural resources. This process actively occurs in Taiwan where the Luzon Volcanic Arc collides obliquely with the passive margin of...
